"TAT teaches drivers to try to spot sullen, hopeless-looking children, teens and young adults. Perhaps they're wearing revealing clothing, or maybe have tattoos like bar codes or men's names that might indicate ownership. The group also promotes a hotline to report trafficking."

Trucking companies are coming on-board as well as law enforcement.

250,000 drivers have been introduced TAT.

Initial results: "calls to the hotline have freed hundreds of trafficking victims."

Some truck stops are on-board too with 24x7 videos playing on monitors, stickers, posters and employees being trained to spot it.
